Box.

SPECIFICATION forming part of Letters Patent No. 269,170, dated December19, 1882.

` Application filed September 18, 1882. (No model.)

Boxes, of which Vthe following description, in

connect-ion with the accompanying drawings,

'isa specication.

My invention relates to the manufacture of boxes of paper or card board,and has for its object i to produce a more satisfactory box at less costof manufacture than has heretofore been done. Boxes have heretofore beenmade from pieces of straw-board cut to rthe proper shape and fastenedtogether by suitable cement or paste to form the body of the box, whichis subsequently covered with paper to give it a suitable finish,thestraw-board affording the stiffness or` body of the box, While thecovering or lining gives it a better appearance to theeye. When boxesare made in this way the operation of pasting the paper upon the box,that is made of straw-board s et up in its ultimate shape or form,meistens the said straw-board, and it is almost impossible to preventbending or distorting the sides and ends of the box in the process ofpasting on the inishing coat of paper, so that the finished box, whendried, is of irregular shape and unsightly appearance.

I have discovered that a box can be made by first coating the dat sheetsof straw-board with the paper that is to give its finished surface, andsubsequently cutting the said surfaced board into the proper shape forthe blanks, creasing, bending, and fastening theV said blanks togetherto form the completed box, the material of which is thus never dampeuedafter it is cut from the flat sheets. In order to enable the blanks tobe properly bent, the straw-board has usually been cut partly throughalong the line that is to be bent, and the coating of paper, that hasbeen put on after the blank of straw-board is set up, covers the rawedges that are produced by thus scoring or partially cnttingthrough thestraw-board. In order to obviate thus cutting the strawboard after ithas been provided with the nishing papered surface in at sheets, inaccordance With this invention, I enable the box to be bent by means ofpressing its surfaces in a double line ou the inside or side towardwhich the fold is to be made', thus causing the fiber on the said sideAto buckle'or crush together, While the fiber on the other side stretchessufficiently to produce the desired bend in the blank without severingthe fibers. As the ber of straw-board is very short and brittle, it willnot always stretch suicientl y to make a good joint When creased andbent, as just` described. To obviate this the outside of that portion ofthe box-blank which is to be bent is covered with a strengthening-layerof Manila or equivalent paper which has a long, tough ber, `the saidManila paper being itself covered with a nishing or surfacing layer ofwhite or other paper of liner quality, togive the desired finish to thecomplete box.

Figure lis a diagram of the blanks for mak- -ing a paper box inaccordance with this invention; Fig. 2, a section of the materialemployed in the said blanks, and Fig. 3 a perspective view of the saidblanks set up to form a complete box.`

The blanks a a b may be of any usual shape, they being eut from materialcomposed, as shown in Fig. 2, of ordinary straw-board or stiffpasteboard, e, and provided on one side with a continuousstrengthening-covering, f, of Manila paper or other paper having a longtough fiber, and the said board thus covered withwManila paper havingsurfaces g on each side, .of white paper or other material, which it isdesired to have appear as the surface of the nished box. `The said blankb is shown as of proper shape to form the bottom of the box, it beingcreased, as shown at 2, to enable the end portions, c c', to be bent atright angles to the bottom portion. The said bottom portion and endportions are each provided with short Win gs or iiaps d, which areenabled, by means of `creases 3, to be turned at right angles to thesaid bottom and end portions to enable the side portions, a a', to beattached to the said bottom and endportions, as shown in Fig. 3, thedifferent blanks a, a', and b being united by paste or cementinglmaterial iu the usual manner. As the blank b is bentat 2 and 3 after itis covered with the finishing or surface paper g, see Fig. 2, the saidIOO and the fiber ofthe Manila paperf on the opposite side stretching,so that no break is apparent in the liber of the blank after being bent.The side pieces, a a', do not have to be creased, and consequently thelayer of manila need not be employed in the stock from which these arecut.

The finished boxes will differ from those made in the usual manner onlyin presenting raw edges at the top of the box and at the ends of theside pieces, a a, and the box will usually be provided at the end with alabel, which Will be slightly Wider than the end of the box, thusoverlapping the side, as` shown at 4, and covering the raw edges whichWould otherwise appear at the end of a box. For most purposes for whichthe boxes yare to be employed the raw edge at the top will not be anobjectionable feature, and the other advantages-namely, of having flattrue sides and separate ends-Will more than compensate for the said rawedges.y

It is obvious that the side pieces, a a', might be made continuous withthe bottom and the .end pieces attached thereto, or that other shapesmight be employed for the blanks Without departing from this invention.

The box will be provided with a cover made in substantially the samemanner.

By the term Manila paper77 I intend to in` ity to a high degree andanswering the purpose excellently in practice.

I do not in the present application claim the herein-described method orprocess of making paper boxes, as I intend to make it the subject ofanother application for Letters Patent.

I claim- 1. A box-blank composed ofa basis of strawboard or pasteboard,provided with a layer of Manila paper on one side and with finishing orsurfacing paper upon its other side and upon the said Manila paper,substantially as described. t

2. A box-blank composed of straw-board having a covering of Manila paperon one side and creased by compression in two paral- NATHANIEL BRAGDON.
